Abstract

The present invention discloses a circularly polarized antenna for an IOT device and an IOT device with the same. The circularly polarized antenna comprises a first radiation portion formed in a plateshape, and a second radiation portion; one end of the second radiation portion is connected to a peripheral edge of the first radiation portion, and in a thickness direction of the first radiation portion, the other end of the second radiation portion spirally extends downwards away from the first radiation portion along the circumferential direction of the first radiation portion. According to the circularly polarized antenna for the IOT equipment, the second radiation portion is connected with the first radiation portion , and the second radiation portion spirally extends downwards in the circumferential direction of the first radiation portion, so that the antenna forms the circularly polarized antenna with omnidirectional receiving capability, and the signal receiving and transmittingperformance of the antenna is enhanced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a circularly polarized antenna for an IOT device and an IOT device having the same. Background technique [0002] It is pointed out in related technologies that IOT (Internet of Things) technology, as an important application scenario in 5G technology, has begun to show more and more potential in various applications. Due to the diversity of IOT terminal nodes and the complexity of the use environment, it poses a lot of challenges to the manufacture of IOT equipment. Many IOT equipment need to adopt protective measures to prevent the environment from harming the equipment, and at the same time, it is necessary to avoid the protective measures adopted to damage the antenna. The signal sending and receiving function will be affected. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior ...
